System and method for filtering program service name data

Abstract

A system and method for filtering Program Service Name (“PSN”) data includes a processor, an antenna in communication with the processor, a display device in communication with the processor, and a memory unit in communication with the processor. The memory unit contains instruction executable by the processor to configure the processor to receive a signal from a wireless source via the antenna, the signal having PSN data, determine if the PSN data is a static PSN or a slowly updated PSN, and display the PSN data on the display device if the PSN data is a static PSN or a slowly updated PSN.

1. A method for filtering program service name (“PSN”) data, the method comprising the steps of:
 receiving a signal from a wireless source, the signal having PSN data; 
 determining if the PSN data is a dynamic PSN, a static PSN or a slowly updated PSN; and 
 not displaying the PSN data on a display of the device if the PSN data is a dynamic PSN and displaying the PSN data on a display device if the PSN data is a static PSN. 
 
     
     
       2. The method of  claim 1 , wherein the step of determining if the PSN data is a dynamic PSN, a static PSN or a slowly updated PSN further comprising the step of:
 receiving a first PSN from the wireless source; 
 determining the amount of time needed to receive the first PSN from the wireless source; and 
 not displaying the PSN data on a display of the device if the amount of time needed to receive the first PSN data from the wireless source was less than a threshold time and displaying the PSN data on the display device if the amount of time need to receive the first PSN from the wireless source is greater than the threshold time. 
 
     
     
       3. The method of  claim 2 , wherein the threshold time is about 2.5 seconds. 
     
     
       4. The method of  claim 1 , further comprising the steps of:
 receiving a new PSN; 
 determining if the new PSN is the same as a previously collected PSN; 
 calculating the time difference between receiving the new PSN and the previously collected PSN if the new PSN is not the same as the previously collected PSN; and 
 displaying the PSN data on the display device if the time difference between receiving the new PSN and the previously collected PSN is less than a PSN change time threshold. 
 
     
     
       5. The method of  claim 4 , wherein the PSN time change threshold is about 6 seconds. 
     
     
       6. The method of  claim 4 , wherein the calculating step is repeated to prevent a false positive error from occurring. 
     
     
       7. The method of  claim 6 , wherein the calculating step is repeated three times. 
     
     
       8. The method of  claim 1 , further comprising the step of displaying blank characters on the display device if the PSN data is not a static PSN or a slowly updated PSN. 
     
     
       9. The method of  claim 8 , wherein the blank characters are a plurality of spaces. 
     
     
       10. The method of  claim 8 , further comprising the step of storing the PSN data for later use. 
     
     
       11. A method for filtering program service name (“PSN”) data, the method comprising the steps of:
 receiving a signal from a wireless source, the signal having PSN data and being a first PSN; 
 determining if the first PSN is a static PSN by determining if the amount of time needed to receive the first PSN from the wireless source is greater than a threshold time; 
 displaying the PSN data on the display device if the amount of time need to receive the first PSN from the wireless source is greater than a threshold time 
 determining if the first PSN is a slowly updated PSN by receiving a new PSN and determining if the new PSN is the same as the first PSN for a period exceeding a validation time; and 
 displaying the PSN data on the display device if the new PSN is the same as the first PSN for a period exceeding a validation time. 
 
     
     
       12. The method of  claim 11 , wherein the validation time is about 6 seconds. 
     
     
       13. A system for filtering Program Service Name (“PSN”) data, the system comprising:
 a processor; 
 an antenna in communication with the processor; 
 a display device in communication with the processor; and 
 a memory unit in communication with the processor, wherein the memory unit contains instructions executable by the processor to configure the processor to receive a signal having PSN data from a wireless source via the antenna, to determine if the PSN data is a dynamic PSN, a static PSN or a slowly updated PSN, and to not display the PSN data on the display device, if the PSN data is a dynamic PSN and to display the PSN data on the display device if the PSN data is a static PSN or a slowly updated PSN. 
 
     
     
       14. The system of  claim 13 , wherein the system is a distributed system.
